Abstract

L'invention porte sur un système réseau auquel sont connectés une pluralité de récepteurs de télévision comportant une fonction d'instruction pour réserver un programme de télévision et un dispositif d'enregistrement. Le système permet à une liste de réservations de programme faite par divers récepteurs de télévision d'être visionnée sur un récepteur de télévision. Le dispositif d'enregistrement crée un code de réservation commun prédéterminé ; reçoit de manière séquentielle des instructions de réservation de programme conjointement au code de réservation commun ; et enregistre les instructions de réservation de programme reçues et le code de réservation commun dans une mémoire. Lorsqu'une liste de réservations est demandée sur un récepteur de télévision, les instructions de réservation de programme sont transmises par la mémoire conjointement au code de réservation commun et la liste de réservations est créée à partir du code de réservation commun.
